Cholera Vaccine

What is Cholera?

Cholera is an acute diarrhoeal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae. It remains a global threat affecting millions of people each year, particularly in areas with inadequate water treatment and sanitation.

Cholera can cause profuse watery diarrhoea leading to severe dehydration and death within hours if left untreated. The cholera vaccine also provides some cross-protection against traveller's diarrhoea caused by enterotoxigenic E. coli (ETEC), which is one of the most common causes of diarrhoeal illness in travellers.

Do I need this vaccine?

Cholera vaccination is recommended for travellers to high risk areas, particularly those working in disaster relief, refugee camps or healthcare settings. It is also useful for backpackers and those travelling to areas with poor sanitation who want additional protection against traveller's diarrhoea.

How many doses do I need?

The cholera vaccine is an oral vaccine taken as a drink. The course consists of 2 doses for adults and children aged 6 and over, taken 1 to 6 weeks apart. The course must be completed at least one week before potential exposure.
